Focused ultrasound technology provides a noninvasive modality for tissue ablation. Although widely used for the treatment of benign prostatic hyperplasia, its application for the treatment of localized prostate cancer is controversial, and its use for the treatment of small renal masses remains experimental. This article outlines the underlying principles of thermal focused ultrasound technology and its limitations as evident in the current literature. The principles and technique of nonthermal cavitational ultrasound tissue ablation is described with a summary of preliminary experimental data.
聚焦超声技术为组织消融提供了一种非侵入性方法。尽管它被广泛用于治疗良性前列腺增生，但其在治疗局限性前列腺癌方面的应用存在争议，而其在治疗小肾肿块方面仍处于实验阶段。本文概述了热聚焦超声技术的基本原理及其在当前文献中所体现的局限性。文中还描述了非热空化超声组织消融的原理和技术，并总结了初步实验数据。
